Command Comments
EXT=
BIOS is loaded from flash. Remove these lines from CONFIG.SYS.
TSR=
Use INSTALL= or execute TSRs from ROMINIT.BAT or AUTOEXEC.BAT.
VERIFY
VERIFY ON, a feature of COMMAND.COM, can be used. But, this command is not
identical with VERIFY. VERIFY causes MINIĆDOS/MAXIĆDOS to write through the disk
buffers and write directory information to the media whenever it changes. These actions do
not occur in DOS. The application is responsible for performing file commits. See
PL/N
Application Changes
(page 6Ć10).
See
Appendix A, Sample Configuration Files
, for an example CONFIG.SYS for a
PL/N application on a 6200 Computer. Also, see the
ROM DOS 5
topic in Section
7 for additional information.
CPLNI.COM
Do not use the ć
d
command line switch. Do not delete driver files from the RAM
drive after they are loaded. All files needed to restart the application after a
reset must remain on the RAM drive.
Add ćc128" to the command line, so the cache is large enough to contain the
entire application program and the entire library resource program. A 4000
Series computer can be configured to minimize executable memory space. The
6000 Series computer has the standard 640 KB provided by DOS, providing
ample space.
PC4800.SYS
Use Version 1.80 or later for a PEN*KEY 6000 Series platform. This driver is
used for NORAND
R
Portable Communications Protocol (NPCP) printer support
for both PL/N and nonĆPL/N applications. 4000API.EXE must be loaded when
PC4800.SYS is used.
PC-DEXIO.BIN
Use the file from PLN4000 version 1.08 or later for a PEN*KEY 6000 Series
configuration. 4000API.EXE must be loaded when PCĆDEXIO.BIN is used.
SYSIO.BIN, TTYIO.BIN, URTIO.BIN
Use the file from PLN4000 version 1.08 or later for a PEN*KEY 6000 Series
configuration.
New 6000 Series Files
The following files are new 6000 Series files that were not used on the 4000
Series platform:
AUTOEXEC.BAT
This is a standard ROM DOS 5 configuration file. See the
ROM DOS 5
topic in
Section 7 for a description of this file.
4000API.EXE
This program provides functionality for certain applications written for the 4000
Series to run unmodified on the PEN*KEY 6000 Series platform.
